Composite fabric sheet for use on sports shoes

ABSTRACT

A composite fabric sheet for use on sports shoes are cut into pieces and sewn to a shoe or openings or holes defined on a shoe. The pieces sewn to an interior side of a shoe cover the openings or holes. The composite fabric sheet has a piece of superficial cloth and a piece of mesh inner cloth. The superficial cloth includes weaving bands and elastic bands that are crisscross interwoven. The weaving bands has proper thickness, width and wear resistance; the elastic bands has proper thickness, width and elasticity to make the interwoven composite fabric sheet extensible either in lateral or longitudinal direction and durable. The inner cloth is an elastic, air permeable mesh sheet which is adhered by adhesive to a back side of the superficial cloth either in the longitudinal or lateral direction in a random manner whereby the superficial cloth of composite fabric sheets sewn to a shoe is extensible along with the elastic inner cloth in wearing. At crossing points of the interwoven weaving bands and the elastic bands free of adhesive and the elastic bands are elastically extend to produce wide ranged buffer air passages so as to obtain wear resistant, durable, elastic, buffer and air permeable features in use.

BACKGROUND OF THE INVENTION

[0001] The present invention relates to composite fabric sheet for useon side faces of a sports shoe, and particularly to a piece of compositefabric sheet sewn to a preset hole or opening on each side face of asports shoe for variation or change in style. The composite fabric sheetis wear resistant, durable, bendable, flexible, extensible and airpermeable in nature. Thereby, such a composite fabric sheet is practicaland comfortable for use.

[0002] In general, there are several kinds of fabric sheets sewn to theinner sides of through holes of a shoe's side faces to make a shoeembodiment varied in styles and appealing to eyes. Such fabric sheetsappear in the following types.

[0003] 1. The first one is illustrated in the U.S. Pat. No. 586,137issued on Jul. 13, 1897, of the so called sanitary shoes. It has anobvious disadvantage in use. The shoe embodiment is made of leather orplastics and has on the side faces a number of longitudinal elongatedslots in parallel to one another with a belt fixed at both ends formedbetween every two slots whereby a plurality of laterally disposed beltsare interwoven in a crisscross manner with the fixed belts to form aplurality of air permeating fissures. These air permeating fissures canfunction well but the interwoven belts are not extensible, causing awearer to feel uncomfortable in walking and wearing.

[0004] Another kind of prior art as shown in the U.S. Pat. No. 3,497,971issued on Mar. 3, 1970 is related to an upper material for shoes. Thismaterial has a disadvantage in practical use. The upper material A ismade up of interwoven belts a, c obtained by cutting a whole piece offabric sheet into a plurality of belts. Then the upper material A is cutinto pieces 2, 3 which are sewn to a shoe embodiment B, the uppermaterial A so produced is not soft and extensible enough to make awearer of such kind of shoes feel comfortable.

[0005] A third prior art relates to a sports shoe made of compositerubber sheet material disclosed in U.S. Pat. No. 4,858,339 issued onAug. 22, 1989. This material has a following disadvantage in practicaluse. The composite rubber sheet is made up of a piece of bottom cloth 3,a sponge rubber sheet 2 of proper depth and a mesh cloth 1 having apercentage of voids in the range of 15 to 75%. The mesh cloth 1 isdeeply engaged with the sponge rubber sheet 2. Such a composite rubbersheet applied to sports shoes has good extensibility, elasticity,durability and wear resistance. However, the sponge rubber sheet 2 haspoor air permeability, making a wearer of the shoes feel uncomfortable.

SUMMARY OF THE INVENTION

[0006] Therefore, the primary object of the present invention is toprovide a composite fabric sheet for sports shoes, which is made up of apiece of superficial cloth and elastic inner mesh cloth, the superficialcloth is made up of a plurality of weaving bands and elastic bands thatare interwoven together in a crisscross manner. Such a composite fabricsheet is extensible and air permeable in practical use so as to make awearer of shoes feel comfortable and convenient.

[0007] Another object of the present invention is to provide a compositefabric sheet for sports shoes. The inner side of the fabric sheet is amesh cloth of elasticity and air permeability and the outer side thereofis made up of interwoven weaving bands and elastic bands whereby widerange air passages can be formed when the composite fabric sheet isforced to extend to make air permeable via the passages, rendering theinterior of a shoe dry and comfortable.

[0008] One further object of the present invention is to provide acomposite fabric sheet wherein as the superficial cloth is extended, inthe inner side at the crossing points of the weaving bands and theelastic bands without adhesive material can be elastically extended tonaturally form a wide range buffer air passages which can absorb compactforce. Thereby, the relative reduction of compact can enhance wearresistance and comfort of shoes.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

[0013] Referring to FIG. 1, the composite fabric sheet 20 of the presentinvention is applied to the side faces of a sports shoe embodiment 10.The composite fabric sheet 20 is made up of a piece of superficial cloth21 and a piece of inner mesh cloth22. The superficial cloth 21 is madeup of weaving bands 211 and elastic bands 212 crisscrossed andoverlapped in the longitudinal and lateral directions to interweavetogether into a composite fabric sheet with a proper thickness and widthand durability.

[0014] The weaving bands 211 are of proper thickness, width and wearresistance. The elastic bands 212 are also of proper thickness, widthand elasticity. After the weaving bands 211 and elastic bands 212 areinterwoven, the superficial cloth 21 of the composite fabric sheet canbe naturally extended in either longitudinal or lateral directions. Theinner mesh cloth 22 is a piece of air permeable mesh cloth provided witha plurality of meshes and is extensible in four directions. As thecomposite fabric sheet 20 is produced, as shown in FIG. 2, thesuperficial cloth 21 is coated with thermal adhesive on the back thereofby thermal rollers so as to permit the inner cloth 22 to be attachedthereto in a random manner or in either longitudinal or lateraldirections. The weaving bands 211 and elastic bands 212 of thesuperficial cloth 21 are partially or alternatively engaged with theinner mesh cloth 22 by adhesive so as to permit the crossing points ofthe weaving bands 211 and the elastic bands 212 to be free of theadhesive.

[0015] Referring to FIG. 3, in assembly, the perspective diagram of thepresent invention shows that the composite fabric sheet 20 is cut intopieces of various shapes in advance for use and the pieces are fixedlysewn to the shoe embodiment 10 or the shoe embodiment 10 is providedwith through holes or openings and corresponding pieces of the compositefabric sheet are sewn to the shoe embodiment 10 from the interior of thesame.

[0016] Referring to FIG. 4, the operation mode of the present inventionis illustrated. The composite fabric sheet 20 of the shoe embodiment 10will extend and deform as a result of the insertion of a foot; at thesame time, at the crossing points of the inner sides of the interwovenweaving bands 211 and the elastic bands 212 are free of adhesive can beextended in the elastic bands direction so as to form a wide rangedbuffer air passages 23 of proper size so as to permit air to passtherethrough.

[0017] There are a number of advantages obtained in the presentinvention given as below:

[0018] 1. The superficial cloth 21 of the composite fabric sheet 20 haselastic bands 212 in the longitudinal or lateral direction and theassociated inner mesh cloth 22 at the bottom is also elastic in nature,permitting the composite fabric sheet applied to shoes to extend. Thus awearer of shoes feels easy to wear and comfortable.

[0019] 2. The inner side of the composite fabric sheet 20 is made ofmesh cloth with elasticity and air permeability; and the outer side ofthe same is made of cloth including interwoven weaving bands 211 andelastic bands 212. As a result of the extension of the elastic bands212, at the crossing points with the elastic bands 212 will form aplurality of air passages whereby ventilation takes place among themeshes of the inner mesh cloth 22, making the interiors of shoes dry andcomfortable.

[0020] 3. When the superficial cloth 21 is extended, the air passagesformed on the inner side without adhesive at the crossing of the weavingbands 211 and elastic bands 212, the elastic bands 212 can extend freelyto form buffer-like air passages 23 which can absorb compact, making thecomposite fabric sheet 20 wear resistant as a result of the reduction ofcompact. It makes a wearer feel comfortable.
